|Manual Testing is not always reliable. Using this method of test execution is not accurate when testers have to verify the same scenario 20 times.
|Automation testing performs the same operation each time.
|Manual testing executed in rgeression testing might not catch defects for frequently changing requriments.
|Automation testing is Very helpful with regressions in testing where code changes frequently.
|Manual testing executed will be useful when the testcase only needs to run once or twice.
|Automation testing is very useful when frequently executing the set of test cases.
|With manual testing, testing on differenct machines with diffrent OS platform combinations cannot be done concurrently. Executing each task requires different testers
|Automation testing can also be done on diffrent machines with diffrent OS platform combinations, concurrently.
|It is very helpful in UI testing.
|Sometimes it's not helpful for UI testing.
|Executing the Build Verification Testing is very mundance and tiresome in Manual Testing.
